There are exactly 2 lines following PATTERN.
I need output to be one line with PATTERN, LINE1 and LINE2 concatenated.
That is, output from input file above should be :
How can such 3 linies be joined using sed or awk ?
Regards,
Hench

Hi guys,
anyone know how can i join multiples lines using sed till the end of a file and output to another file in a single line?
The end of each line will be replaced with a special char "#".

Hi,
I lack the utter fundamentals on how to craft an awk script.
I have hundreds of text files that were mangled by .doc format so all the lines are broken up so I need to join all of the lines of text into a single line. Normally I use vim command "ggVGJ" to join all lines but with so many... (3 Replies)

LEARN ABOUT SUSE
pdl::opt::simplex
Simplex(3) User Contributed Perl Documentation Simplex(3)NAME
PDL::Opt::Simplex -- Simplex optimization routines
SYNOPSIS
use PDL::Opt::Simplex;
($optimum,$ssize) = simplex($init,$initsize,$minsize,
$maxiter,
sub {evaluate_func_at($_[0])},
sub {display_simplex($_[0])}
);
DESCRIPTION
This package implements the commonly used simplex optimization algorithm. The basic idea of the algorithm is to move a "simplex" of N+1
points in the N-dimensional search space according to certain rules. The main benefit of the algorithm is that you do not need to calculate
the derivatives of your function.
$init is a 1D vector holding the initial values of the N fitted parameters, $optimum is a vector holding the final solution.
$initsize is the size of $init (more...)
$minsize is some sort of convergence criterion (more...) - e.g. $minsize = 1e-6
The sub is assumed to understand more than 1 dimensions and threading. Its signature is 'inp(nparams); [ret]out()'. An example would be
sub evaluate_func_at {
my($xv) = @_;
my $x1 = $xv->slice("(0)");
my $x2 = $xv->slice("(1)");
return $x1**4 + ($x2-5)**4 + $x1*$x2;
}
Here $xv is a vector holding the current values of the parameters being fitted which are then sliced out explicitly as $x1 and $x2.
$ssize gives a very very approximate estimate of how close we might be - it might be miles wrong. It is the euclidean distance between the
best and the worst vertices. If it is not very small, the algorithm has not converged.
FUNCTIONS
simplex
Simplex optimization routine
($optimum,$ssize) = simplex($init,$initsize,$minsize,
$maxiter,
sub {evaluate_func_at($_[0])},
sub {display_simplex($_[0])}
);
See module "PDL::Opt::Simplex" for more information.
CAVEATS
Do not use the simplex method if your function has local minima. It will not work. Use genetic algorithms or simulated annealing or
conjugate gradient or momentum gradient descent.
They will not really work either but they are not guaranteed not to work ;) (if you have infinite time, simulated annealing is guaranteed
to work but only after it has visited every point in your space).
